We develop and manufacture custom-configured STS 125 stacker trolley systems, engineered to perform in complex shipyard environments and industrial logistics operations.
Stacker trolley composition:
- Self-propelled modular trolleys engineered for synchronized load handling.
- Autonomous hydraulic power units (HPUs) powered by electric or diesel engines for flexible deployment.
- Track-based hose carriers ensuring safe routing of high-pressure lines.
- Rigid mechanical interconnections between trolleys for structural alignment and coordinated movement.
- Complete hose kits featuring high-pressure quick-coupling connections for fast installation.
- Marine-grade under-keel support beams ensuring secure vessel positioning.
- Heavy-duty longitudinal support beams distributing load evenly across the system.
- Cross-beam locking modules maintaining system rigidity under dynamic loads.
- Hydraulic centering mechanisms for precise positioning and load balance correction.
Our company supplies advanced stacker transport systems tailored to modern automation and heavy-load handling demands in shipyards and production workshops.
The STS 125 trolley system facilitates secure and efficient ship movement on slipways, dry docks, or industrial platforms and is ideal for transporting heavy-duty items such as engine modules or steel structures.
Features and benefits
We offer models configured for load capacities up to 125 tons, with optional upgrades available for increased payloads up to 420 tons. Trolley systems are available in self-propelled or non-driven configurations, suitable for both freshwater and seawater operations.
The STS 125 model strikes a balance between compactness and capability—designed to operate in tight spaces while offering stability and control across rough terrain or variable surfaces.
Technical highlights include:
- Integrated rotating axles and hydraulic jacks for precise elevation control.
- Remote control capability for safe descent and maneuvering.
- Hydraulic synchronization system ensuring uniform pressure distribution between trolleys.
Each trolley features hydraulic load-balancing cylinders, enabling fine-tuned redistribution of weight across the unit group and enhancing overall system safety during operation.
The system can be configured as electric or hydraulic, depending on operational requirements. Non-powered variants are maneuvered using external winches or towing devices.
Hydraulic architecture can be centralized via an external pump station or decentralized with onboard hydraulic circuits integrated into each trolley unit.
Custom equipment development
When selecting a ship transfer platform, it is vital to ensure that each component meets your specific load, terrain, and project requirements. Our company offers:
- Competitive pricing aligned with technical scope and delivery timelines.
- Detailed specification and estimation workflow with timely client coordination.
- Factory pre-delivery testing for full quality assurance prior to shipment.
- Decades of experience developing modular heavy-transport systems for marine and industrial use.
The STS 125 trolley system is adaptable to various track gauges, ranging from 1000 mm to 1580 mm, ensuring seamless integration into existing infrastructure. Our modular, high-load ship transfer systems are engineered for reliability, safety, and operational precision.
